Iron has a density of 7.86 g/cm3. calculate the volume (in dl) of a piece of iron having a mass of 4.07 kg . note that the density is provided in different units of volume and mass than the desired units of volume (dl) and the given units of mass (kg). you will need to express the density in kg/dl (1 cm3 = 1 ml) before calculating the volume for the piece of iron.

The volume of the piece of iron is 5.18dL.

Explanation:

The density (ρ) is equal to the mass (m) divided the volume (V).

If we rearrange it, we have:

To express the volume in dL we will need the following relations:

Then,

Finally,

c. because step up transformer steps up the input voltage i.e increases the input voltage  

the number of turns are greater on the secondary side of step up transformer  

transformer does not handle dc current

a boiling water reactor does not boil the water. a pressurized water reactor boils the water faster. a pressurized water reactor is heated directly by the core. a pressurized water reactor does not use fission.
